Application filed August 1,1901. Serial No- 70,451. (No model.)

To aZZ whom it may concern.-

Beit known that I, DAvID GROTTA, residing at Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Machines'fon Passing Ribbon Through Insertion, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and I0use the same.

My invention relates to machines for passing ribbon or tape throughinsertion to be used on undergarments and other wearing apparel, andespecially on corsets.

The object of myinvention is to produce a machine by which the ribbonmay be passed through the openings in the insertion in a quick andefficient manner.

The invention will be readily understood from the following description,taken in connection with the accompanying drawings, forming a part ofthis specification.

Referring now to the drawings,in which like symbols of referenceindicate the same parts,

Figure 1 is a vertical section taken lengthwise of the machine. Fig. 2is a vertical transverse section taken on the line 2 2 of Fig. 1. Fig. 3is a detail showing the needle in a different position on the rollerfrom that 0 shown in Fig. 1. Fig. 4 is a side elevation, on a similarscale, of the machine. Fig. 5 is a plan view of Fig. 4; and Fig. 6 is aplan view of a section of the insertion, showing the ribbon passedtherethrough.

5 In the drawings the part lettered A represents the bed of the machine,having raised guides B B on each side thereof, between which passes theinsertion after it leaves the rollers, hereinafter to be described.

0 0 represents guides for the insertion before it enters the rollers.These guides are pivoted on links 0, so that they may be adjustcd fordifferent widths of insertion.

Mounted on the bed of the machine in suit- 5 able bearings is a rollerD,having on one end of its shaft a pulleyD around which passes a band orbelt by which the roller is rotated in a well known manner. This rolleris grooved at D, and projecting from the grooves machine and over theroller.

above the periphery of the roll at equal dis- 5o tion through which theribbon is to be passed when the insertion is passing through the Each ofthese spurs is slotted vertically, as shown at D the bottom of the slotbeing of such shape as to leave an incline or cam D beginning at a,

at the bottom of the groove D and extending up to the point b, above theperiphery of the roller and about half-way the length of the spur.

E is a guide-roll located above the rollerD and journaled in a frame F,pivoted at G to a bracket H, attached to the bed of the machine. Thisroll has a groove E therein, into which the spurs D enter when the rollis rotated, as shown in the drawings.

I J are two clamps for holding the needle,

to be hereinafter described. The clamp I is pivoted to the guide B atthe point I. The clamp J is rigidly attached to said guide B. Each ofthese clamps is made in two parts or jawst'c" and jj. Passing throughthesejaws are clamp-screws I andd Between the jaws of the clamps is heldwhat I term a hollow needle K, the end K of which is bent or curvedandbears against the bottom of the groove D of the roller D, as shown inthe drawings. This needle has a hole or slot K therein, through whichpasses the ribbon or tape L, which is on a roll M, journaled in asupport N, attached to the bed of the ma.- chine. I

At one end of the bed of the machine is attached a bracket 0, havingjournal-bearings 0, into which may be inserted the journal or spindle Oof the roller 0 whichI term the feed-roll, around which is rolled theinser- 0 tion or lace 0 At the other end of the machine is what I termthe take-up roll P, journaled in a bracket or support P, attached to thebed of the machine. Around this roll is wound the insertion after it haspassed through the machine and the ribbon or tape inserted therein, thetake-up roll being turned by the crank P The lace or insertion has holesor openings 0 therein at equal distances apart, through which the ribbon L is inserted.

Q is a guide pin or roll adjacent to the roller 13 and under which theinsertion passes before it is taken up by the roller D.

Having described the construction of the machine, its operation will nowbe set forth. The feed-roll D, having the insertion wound thereon, isinserted in its bearings in the bracket 0. The end of the insertion isthen led between the guides C, under the guidepin Q, and around theupper surface of the roller D, the spurs D of this roll entering andpassing through every other one of the openings O in the insertion. Theroller D is then turned by hand and the end K of the needle passed, forexample, up through the first opening 0 and then down through the nextopening, and then up through the next, and so on for three or fouropenings. This is in order to properly start or thread the insertion onthe needle. Supposing now the needle has just been passed down throughone of the openings 0 and is restingon the bottom of the groove D withits extreme end, which is slightly upturned at the beginning a of thecam in the spur, as shown in Fig. 1 of the drawings, upon power beingnow applied and the roller caused to be rotated in the direction of thearrow the cam cab in the spur will raise the end of the needle, theclamp I being pivoted, so that the needle will be permitted to have avertical movement or vibration and cause it to pass up through theopening 0 through which this spur is passed. WVhen the spur passes fromunder the end of the needle, the needle will have passed through thisopening 0 in the insertion, and as the roller continues to rotate willdrop down in the groove in the roller between the spurs, carrying withit that part of the insertion lettered c, and the point of the needlewill enter the next opening between i the spurs from above, and as theroller rotates the end of the needle, which is now resting on the bottomof the groove under the insertion, as shown in Fig. 3, will come incontact with the cam in the next spur and be raised up through the nextopening on the next spur. As the roller continuesto rotate thisoperation is repeated, and the insertion is strung on the end of theneedle, which passes up through one hole and down through the other, asdescribed, and shown in Figs. 1

and 3 of the drawings. As the needle is held by the clamp I, theinsertion cannot pass beyond said clamp, and as the roller continues torotate and thread the insertion on the needle it will be banked up orfolded between the roller and the clamp. When there are several folds onthis part of the needle, the clamp-screws are turned to unclamp the jawsfrom the needle, and the folded part of the insertion is then pushedalong by-the hand of the operator beyond this clamp to the left, asshown in Fig. l of the drawings, and the clamp is then reset on theneedle. This operation is repeated until the folds are banked up betweenthe clampsI and J, when the clamp J is then loosened from the needle byturning its clamp -screw J and the folds pushed along by hand on thatsection of the needle between its end and the clamp J. The end of theribbon L is then pulled down from the roll M and inserted in the openingK and passed through the needle and left as shown in Fig. 1, where itcomes out at the left end of the needle, as shown in the drawings. Theoperatorthen takes hold of the end of the insertion and the ribbon,fastens them to the roll P, and winds them on a take-up roll by turningthe crank P the ribbon coming off the roll M and through the needle asthe insertion is wound on the roll. When that part of the ribbon whichis in folds between the slot K and the end of the needle is wound on thetake-up roll, so that there will only be a straight part of the ribbonbetween the slot K and this roll, the operator ceases turning thetake-up roll, cuts the ribbon at points say Z-so that there will be anend of the ribbon projecting out of the slot of the needle. The operatorthen unclamps the clamp J from the needle (in the meantime the clamp Ihaving been removed and the folds pushed along between the two clamps)and pushes another section of the fold to the left between the opening Kand the end of the needle. The ribbon, which has been out at Z, is thenjoined togetherby needle and thread, for exampleand the crank on thetake-up roll turned to wind thereon that part of the folded insertionbetween the end of the needle and the slot or opening K This operationis repeated until all the insertion on the feed-roll has been passedthrough the machine and wound on the takeup roll with the ribboninserted therein.

It is understood that the roller D is readily removed from its bearings,so as to replace it by another roll with the spurs closer together orfarther apart, so as to operate on lace or insertion having the openingsat different distances apart from that illustrated in the drawings. Itis also understood that minor details may be varied in my inventionwithout departing from the spirit thereof.
